ORE-SEPARATOR.

Specification of Letters Patent.

Patented March 10, 1908'.

Application filed June 24, 1907'. Serial No. 380,536.

T o all whom it may concern:

Be it known that l, JAMES R. YoUNT, a citizen of the United States, residing at Nyssa, in the county of Malheur and State of Oregon, have invented a new and useful Ore-Separator, of which the following is -a specification.

This invention relates to ore separators and more particularly to means whereby fine or float gold may be separated from the undesirable material commingled therewith7 the separation, being thoroughly produced in a simple and eflicient manner.

One of the objects of the invention is to provide riiiies of novel construction and arrangement designed to so direct currents of water as to thoroughly separate and retain free gold carried thereby.

With these and other object-s in View the invention consists of certain novel features of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claims.

In the accompanying drawings is shown the preferred form of the invention.

In said drawings: Figure l is a longitudinal section through a separator constructed in accordance with the present invention. Fig. 2 is a plan view thereof. Fig. 3 is a detail view of one of the rifes. Fig. 4 isa longitudinal section through a portion of a modified form of se arator.'

Referring to the ggures by characters of reference, 1 designates a sluice, the bottom of which is preferably inclined and covered witha coarse fabric such as carpet, canvas, or the like and which has been indicated at 2. Suitably supported upon the` side walls 3 of the sluice and depending between them are riflies of novel form. consists of a top bar 4 the ends of which are preferably seated upon the walls 3 as shown particularly in Fig. 2. ward from the bar is a deflecting member 5 integral with the bar and having) its lower portion curved rearwardly and eveled at its extremityas shown at 7. Another member 8 is also formed integral with the bar 4 and depends therefrom, the lower portion of this member being curved forwardly and slightly upwardly to form a pocket 9 which is for the purpose hereinafter set forth. A deflecting member 5 extends below the pocket 9. Any desired number of these riflles are employed but all of them are of Each of these riflilesv Extending downy different heights. The smallest riffle is placed adjacent the inlet end of the sluice and the riles gradually increase in size toward the `other end thereof. It will therefore be apparent that the distance between the bottom of the sluice and the riffles gradually diminishes toward the discharge end. The deflecting members 5 are preferably positioned with their lower extremities beneath the pockets 9 of the adjoining rifiies and therefore passages are formed between every two adjoining deflecting plates, said passages extending over the pockets located between said plates. lt is to be understood of course that the two members 5 and 8 extend throughout the width of the sluice so that it is only possible for water to pass beneath the riiiies.

With the arts arranged in the manner shown and escribed the separation of the gold is effected by directing a stream of water bearing fine or iioat gold into the upper end of the sluice. A portion of the water will be directed against the members 5 and will be deflected upward thereby. A swirling action is therefore roduced between each member 5 and the adjoining pocket 9 and the gold is precipitated within the pocket. It is of course to be understood that this swirlin action occurs successively between the ri es inasmuch as the passage for the water is reduced in size by each successive riffle. Any float gold remaining in the water after the first riffle is passed will be carried into the second and successive rifiies until all of it has been separated and 'deposited within the ockets 9. Heavy undesirable particles will) be carried off under the last riflie and any values reci itated within the sluice will be retainedp by t e fabric 2. It is of course to be understood that it is unnecessary to provide the last riiile, which has been indicated at 10, with a pocket 9.

Instead of forming the sluice with a flat bottom said bottom can be waved or corrugated as shown at 11 in Fig. 4. When the bottom is thus formed the separation will be facilitated because portions ofthe values will be retained within the grooves formed by the bottom and said serrations will also assist in directing the water upward between the riffles. With either of the constructions described a grizzly, such as indicated at 12, may if desired be placed over the riflies. This grizzly is of course removable so that access may be readily had to the riHes for the urpose of cleaning them.

gaat is claimed is:

l. The combination With a sluice; of a plurality of riflles suspended therein, each riftie comprising a deiecting member and a pocket member, the delecting member of each riHe being disposed below the pocket member of the adjoining riflle.

2, The combination with a sluice, of a plurality of riffles suspended therein, each rifHe comprising a cross bar and de ending oppositely curved members integra there- With, one of said members constituting a deflector and the other member constituting a gold retaining pocket.

orming a water passage thereunder, each rifHe comprising a delecting member curved toward the sluice inlet, and an oppositely extending member constituting a gold retaining poclet, each pocket being dis osed above the deiiecting member of the arl-)joining riHe.

4. The combination With a sluice having a fabric covering on the bottom thereof; of a plurality of riHes suspended Within the sluice and forming a Water passage thereunder radually diminishing in size toward one enr? of the sluice, each riii'le com )rising a deiiecting member curved toward the sluice inlet, and a shorter oppositely extending member constituting a pocket.

5. The combination with a sluice having a Waved bottom and a fabric covering thereon; of a plurality of riiiies suspended within the sluice and forming a water passage thereunder gradually dimmishinfr in size toward one end of the sluice, cach riiIie comprising a deiecting member curved toward the sluice inlet, and a shorter oppositely extending i member constituting a pocket, anda cover l upon the rililes.

l l top bar, a depending delecting member integral therewith. and curved in one direction, and a shorter o positely curved member inf tegral with the ar and constituting a retainl ing pocket, said ,l extend throughout the Width of a slnice. In testimony that I clann the forogonlg as my own, I have hereto affixed my signature in the presence of two Witnesses.
